Engine oil Mobil or PENNZOIL

I've been using Mobil 1 0w30 in my NA 2018 CX5 for 180,000 miles , no issues and runs quieter than 0w20 .

Pennzoil ultra platinum 5w-30 in my 2016. Will use it in wife's 2025 when warranty is done.

My daughter has a 2016 Civic bought new. First oil change was at 200mi with Mobil1 Extended, and then oil/filter changes at 15,000 or 20,000 mile intervals until 86,500. Switched to Restore and Protect and after 1k miles I changed the filter and cut it open, there were zero sludge deposits, and oil color looked new.

I'm fairly sure Mobil1 makes the Toyota branded oil, which is what I'm running in my 2023 Hatchback XSE. I'm using the Toyota 0W8. I also plan on keeping my car for as long as the wheels turn.

Exactly. Change the oil pressure switch. I would spend $50 and get an oil pressure test set with gauge and check pressure to be sure. Oil must be synthetic that meets proper spec. 5w-40 mobil1 European does.

I've been using Mobil 1 10w30 regular and now High-Mileage Synthetic for decades and most of the Jeeps life.

There’s been a lot of advancements in oils since the YJ was new. I use Mobil 1 0w40 in mine due to its excellent temperature range and proven endurance.

Mobile 1 full synthetic 0W-20 every 5K. My engine hums like a top.

My wife drove her 2008 Passat 2 miles per day for six years. As you can imagine, during these very short drives in winter, the oil became diluted - this was born from sever UOAs. So, I changed the oil every 1,500 miles and the oil and filter every 3,000 miles. Over-kill perhaps but based upon my personal expectations, worth the time and money. We used Mobil 1 0W40....which sheared to a 0W30 fairly quickly and stabilized.

I used to use M1 0-40 in my VR6 Corrado, but the valve, chains and engine noise went way up, especially at a cold start
